We played with FlexConnect for a number of months but still could not get what we needed it to do on a consistent basis. Essentially we wanted FlexConnect to drop users into their building VLAN so they would be able to easily interact with the same devices that the wired connections in the buildings could see. As I'm sure you know, this also resolves many of the Apple, Chromecast, etc., problems.
We did have one caveat though that we just couldn't get past -- we wanted to drop faculty/staff into one VLAN and students into another (we can easily return the proper VLAN for a particular client in a particular building from Radius server - FreeRadius with a call to our LDAP server for info) but we also need to send everything else back to the controller for central switching (e.g., police connections, special bar-code scanners that roam and serve to identify a user, but not being used for client traffic, for example, to give out free flu shots to eligible folks or let folks into a sporting event). We just couldn't get past having 95+% locally switched and the remainder centrally switched for over 200 buildings many with now over 100 APs each without using FlecConnect groups which are limited to numbers way too small for our campus. We can even live comfortably without roaming between buildings. MOst folks are not used to being able to roam between buildings downtown or many cannot roam between apartments off campus. How did you get around the FlexConnect group problem? ========================== -jcw ________________________________ From: The EDUCAUSE Wireless Issues Constituent Group Listserv [[email protected]] on behalf of Hector J Rios [[email protected]] Sent: Tuesday, March 17, 2015 9:27 AM To: [email protected] Subject: Re: [WIRELESS-LAN] ResHall Wireless I tested FlexConnect on 8.0.110.0. Here are my observations: *Great alternative to switch data locally (obviously) *No AVC Support *When controller is down, AP goes into standalone more. Must make sure that AP is not able to reach any other controller you don’t want. This was fixed with an ACL. *Client details page does not show client IPv6 address. Client still gets IPv6 address. (PRIME does show it if you run a report). *Client details page does not show VLAN ID. *Putting AP in FlexConnect mode does not require reboot (Cool!) *No IPv6 ACL support More testing to do, but so far so good. -Hector From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[email protected]] On Behalf Of Hector J Rios Sent: Thursday, March 12, 2015 11:13 PM To: [email protected] Subject: Re: [WIRELESS-LAN] ResHall Wireless We use Cisco’s wireless solution with WiSM2s and a variety of WAPs. We actually implemented the guest anchor controller solution last year with dual controllers (WLC2504) and we’ve been happy. I like Britton’s idea of using FlexConnect at the dorms to switch the student data locally. However, I believe there are some limitations that would keep us from using it such as no support for AVC, and some limitations on IPv6. -Hector From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[email protected]] On Behalf Of Osborne, Bruce W (Network Services) Sent: Thursday, March 12, 2015 7:42 AM To: [email protected]<mailto:[email protected]> Subject: Re: [WIRELESS-LAN] ResHall Wireless Hector, You do not say what wireless solution you are using. Let me assume a Cisco or Aruba controller based solution. You can have vlans from your controller tunnel to an anchor controller in a DMZ. Use 802.1X authentication based on AD groups. This solution permits controlled internal access and, if you desire, unfiltered Internet access. Until recently, we did something similar with our open Guest wireless network on our Aruba system. We now use a different solution for this. The anchor controller idea was based on Cisco wireless training several years ago. At that time, it was their recommended guest solution.

In terms of geography, we have 21 ResHalls that are in the perimeter of our campus. Some of these buildings are next to academic or administrative buildings. Eduroam is our main SSID. So, for the longest time it has only made sense to broadcast eduroam everywhere. Now, on the wired side of the house, our ResHalls have a dedicated connection that gives them direct, non-firewall access to the internet (for access to campus resources, a student must VPN). This came about as a request from the students to have more freedom in their residence. Makes sense. But wireless is different as it goes through our campus core, traverses our perimeter firewall, and goes out our main internet connection. I’ve struggled to find an alternative solution to this. We recognize that students in ResHalls are different in the sense that they pay for a place to live and should get an internet service that is similar to their home service. However, any alternatives that we have considered (separate SSID, dynamic VLAN assignment, user groups) just seem to complicate the setup. Any good ideas out there or creative ways in which you have tackled this challenge?
